Apparatus for connecting tubes

ABSTRACT

A tube connection apparatus for use with larger diameter flexible tubing particularly for hazardous material removal comprising an outer tapered sleeve and an inner tapered sleeve that is sized to snugly fit within the outer tapered sleeve and to engage the flexible tubing therebetween. A retainer ring is provided to secure a second flexible tube to the outer tapered sleeve and a transportable wall section which holds the sleeves may be positioned in a passageway of a building and tubing from spaces on either side of the passageway be connected.

BACKGROUND OF THE INVENTION

This invention relates to a tube connector for larger diameter flexible tubing which is used in industrial applications for removing hazardous waste materials including asbestos from buildings constructed in eras gone by.

There are many types of tube connectors known for various tubing. Moreover, there are make-shift field installations for larger diameter flexible tubing using spray adhesives, staples, and duct tape which the current invention is designed to replace.

A representative tube connector is shown in U.S. Pat. No. 3,207,538 issued in 1965 to Pattillo provides a clamp type connector for sheet metal. Another design is shown in U.S. Pat. No. 2,944,840 issued in 1960 to Wiltse which utilizes a tube coupling having a reinforced seal and locking rings. U.S. Pat. No. 5,316,350 issued in 1994 to Kolenbrandt et. al. discloses a tubing with two projecting members for joining and an undercut that receives a locking member of the tube. Unlike the instant invention, Kolenbrandt et. al. is designed for attaching sockets to a tube as opposed to joining tubes by a connector, as is taught by the instant invention.

U.S. Pat. No. 5,333,910 issued in 1994 to Bailey discloses a hose fitting with ring holder having a conically shaped receiving end adapted to receive a flexible hose with a shallow groove for storing an elastic ring which secures the union. Also see U.S. Pat. No. 4,579,375 issued to Fischer et. al. in 1986 for sheet metal duct system having a transverse flange and circumferential clipping means. Furthermore, of general interest are U.S. Pat. No. 4,451,070 issued to Sauer in 1984 for a hose coupling involving an overlapping external collar with an elastic clamping means; U.S. Pat. No. 3,891,250 issued to Oetiker in 1975 for a tubular hose connection and external clamping with overlapping tubular members and an external clamp ring.

See also U.S. Pat. No. 4,037,682 issued to Thorpe et. al. in 1977 for flexible ducting joint employing an arrangement of single ring and interlocking pair of parallel rings with an external binder.

Some of the drawbacks of these designs are that they require tools for connecting and are not designed to connect larger diameter (on the order of magnitude of 12 inches) flexible tubing. They are limited in their use with standard cylindrical tubes with augmented nubs or flanges which are utilized by some of the above patents to lock the tubing in place and assembled tube connection apparatus is easily detachable for removal and disassembly.

To alleviate this problem, and others which will become apparent from the disclosure which follows, the present invention conveniently connects two sections of flexible tubing without the need for tools.

The citation of the foregoing publications is not an admission that any particular publication constitutes prior art, or that any publication alone or in conjunction with others, renders unpatentable any pending claim of the present application. None of the cited publications is believed to detract from the patentability of the claimed invention.

ADVANTAGES OF THIS INVENTION

Unlike the foregoing devices which teach coupling devices that support specially fabricated tubing having nubs, recesses, and locking structures, the instant invention connects standard industrial larger diameter tubing detachably without the need for tools.

The instant invention provides an efficient and convenient means of detachably connecting larger diameter tubing in the field for the removal of hazardous material. Because the connection provided by this invention will not give way during use, as current systems with adhesive and tape do, a safety advantage results.

Still other advantages will be apparent from the disclosure that follows.

Additionally, the foregoing methods for connecting may further include the following additional step of receiving a lateral section of the outer tapered sleeve in an aperture disposed in a transportable wall section.

As previously mentioned the securing of the transportable wall section in a passageway in a building, a vehicle or other structure is also disclosed.

When the passageway is a door in a building, flexible tubes from different rooms may be connected. When the passageway is a window of a building, a flexible tube in the building may be connected with a second flexible tube from outside of the building. Thus, a flexible tube on one side of the passageway may be connected to a second flexible tube on the other side of the passageway.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. Those skilled in the art will appreciate that the conception upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.

While this invention has been described in connection with the best mode presently contemplated by the inventor for carrying out his invention, the preferred embodiments described and shown are for purposes of illustration only, and are not to be construed as constituting any limitations of the invention. Modifications will be obvious to those skilled in the art, and all modifications that do not depart from the spirit of the invention are intended to be included within the scope of the appended claims.

These together with other objects of the invention, along with the various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the invention.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

The wall section can be constructed from any suitable material of construction which can support the tube connection apparatus, associated flexible tubing and the flow of fluid therethrough.

The tube connection apparatus can be made from a high density polyethylene industrial can of the type made by Ropak Corporation of California that has a lid and a generally conical sidewall tapering inwardly from a top rim having an outwardly radiating flange to a bottom surface. The inner tapered sleeve is a bottom portion of the industrial can after laterally cutting said bottom portion from the industrial can and removing said bottom surface. The outer tapered sleeve is the remaining conical portion of the industrial can with the bottom portion removed. The bottom end of the inner tapered sleeve may be inserted into a top opening defined by the top rim of the outer tapered sleeve and moved in the direction of the opposite end of the outer tapered sleeve to affect a snug fit between at least a portion of an outer surface of the inner tapered sleeve and at least a portion of an inner surface of the outer tapered sleeve.

Furthermore, the means for connecting a second flexible tube to the proximal end of the outer tapered sleeve comprises the outwardly radiating flange disposed on the top rim of the outer tapered sleeve and a ring made from the lid after cutting away a central portion of said lid and further cutting at least one partial slit in an outer edge of the ring to allow said ring to flexibly expand over the flange and the second flexible tubing.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
